Weight does not necessarily proportion to speed, especially in boxing :D
 Ray has had boxing as his focus for over ten years of his life. Plus, technique is only part of the speed. A good deal of it comes from muscle that Nick has not had the chance to build up yet. 

In any case, knowing the theory of boxing or fighting or how a person moves is useless once in the fight itself. Fighters have spent years studying each other, and in the end they still end up having to improvise on the go. If learning how to fight was all a person needed, then there wouldn't be anymore knockouts, and what fun would that be? xD

Ahh of course, but the ability to put a theory to physical movement is something that most people cant do, thats why the need to 'drill' to train their body to 'remember' how to move, even if their mind already knows how it works. Nicholas has a superhuman ability to bring that altogether in a way that nobody else can.

This is a subset of 'clarity' the ability to learn isnt just the speed in which he picks things up, its the way he learns.

But I do take your point he may not be as fast just down to his weight, but I believe Nick is very agile anyway, regardless of his powers.
definatley not as explosive as ray though.

And as you say 'improvising' on the go is where Nick is actually miles ahead, as improvising is learning and reacting on the spot, which Nick's power allows him to do much more quickly and efficiently then anybody else.
